VANDENBERG AIR FORCE BASE, Calif. — The Department of War released a PDF on May 8, 2026, under the PURSUE archive. It is titled “DOW-UAP-D49, Launch Summary, Vandenberg AFB, 2000.” The document itself is older. Much older. It covers launches from December 16, 1958, through February 3, 2000. That last date, February 3, 2000, is listed as the incident date. No specific incident location is provided.
The PDF comes from the war.gov domain. It is 8.7 megabytes. Your browser might not show it. Download it. It is a launch summary book. The 30th Space Wing Office of History prepared it. The foreword is signed by Jeffrey Geiger, a historian from that office. He writes: “This is the official registry of all major launch operations conducted from Vandenberg Air Force Base, California. The vehicles are presented in chronological order beginning with the first launch on 16 December 1958. Launch dates reflect Vandenberg local time.”
Geiger’s statement is blunt. It is a registry. No more, no less. But the document’s release now, in 2026, is what matters. It landed in the PURSUE archive. That archive is a Department of War transparency effort. The original document sat in a file somewhere for twenty-six years. Now it is public.
The document has a distribution list. Thirty recipients. They range from Headquarters USAF to NASA. Contractors are on it too: Boeing Defense & Space Group, Aerospace Corporation, Jet Propulsion Laboratory. These are not minor players. This was not a casual internal memo. It was an official record sent to the highest levels of American space and defense infrastructure.
Inside the PDF are two matrices. One is “ANNUAL LAUNCH SUMMARY BY BOOSTER.” The other is “ANNUAL LAUNCH SUMMARY BY COMMAND.” There is also a “LAUNCH FACILITY GUIDE” and a “GLOSSARY.” Geiger’s foreword includes a caveat. The cumulative numbers reported by booster and command “represent only Vandenberg operations.” They do not include, for example, “Titan IV launches conducted on the East Coast at Cape Canaveral, Florida.” That matters. Vandenberg is a West Coast base. It handles polar orbits and classified payloads. Cape Canaveral handles the rest. The document is not a full picture of American launches. It is a slice. A specific slice.
Why release it now? The Department of War did not say. No press conference. No statement. Just a PDF on an archive site. The document itself is straightforward. It is a book of records. But records of this kind, from a base like Vandenberg, do not usually see daylight. Vandenberg has been a hub for National Reconnaissance Office launches, for missile tests, for space shuttle polar missions that never flew. The base is secretive by design. This document breaks some of that silence.
It covers forty-two years of launches. From 1958 to 2000. That is the Cold War and its aftermath. It is Thor rockets and Atlas boosters and Titan missiles. It is the early days of American spaceflight, when everything was military first, science second. The document does not say what the payloads were. It does not name the satellites. It just logs the launches. That is enough. For historians, for journalists, for anyone watching the sky, it is a skeleton key.
The PDF is large. 8.7 megabytes. That suggests scans of original pages, not just text. The original document was printed, bound, distributed. Someone at the 30th Space Wing Office of History typed it up, made copies, mailed them out. It was a working tool. Now it is a historical artifact.
The release date is May 8, 2026. That is a Friday. Governments often dump records on Fridays. Fewer people watch. Fewer questions get asked. But the document is out. It can be downloaded. It can be read. It can be analyzed.
Vandenberg’s first launch was December 16, 1958. That was a Thor missile. The base was new. The space race was on. The last launch in this document is February 3, 2000. That is the incident date. What happened that day? The document does not say. It just marks the end of the registry. Maybe the 30th Space Wing stopped keeping the book this way. Maybe they switched to digital. Maybe something else happened. The document does not answer that. It is a record, not a story. But the story is in the record.
